SAFETY-RAZOR FRAME.

To all whom it mayooncem Be it known that 'LwWILLIAM F. GRosorrorr,

Safety-RazorFrames, of which the following is a full, clear, and exact description.

This invention relates to improvements in safety-razor frames, one of the main objects of the invention being to provide a universal safety-razor frame that is adaptedto hold various. styles of blades. While my .improved frame is adapted for use bythe publie in general, -it is more especially intended for soldiers in the field or in camp. For instance, a soldier may be provided'with a Gilletteshaving outfit, but may not be able to obtain blades for the Gillette frame, and blades of other makes cannot be used. For instance, a Star safetya'azorblade cannot be-used in a Gillette frame, or'viceversa.

My improved razor-frame is arranged to hold blades of any of the popular shaving outfits, for instance, the Gillette, the Star heavy blade, theStar wafer blade, the Gem or thePenn blades, or others of a similar type. I will now proceed to describe my invention in detail, the novel features of which I will point out'in the appended claims, reference being had to-the accompanying drawing, forming part hereof, wherein- Figurel is a 'top' planview of my improved safety-razor frame, the handle being broken away; I I 1 Fig. 2 is a side elevation thereof; Fig. 3 is a rear view of the frame, the handle being removed;

Fig. 4 is a front view of the razor-frame; Fig. 5 is. a partial perspective viewof the clamping element of the frame;

Figs. 6, 7, 8 and 9 illustrate blades of dif- I ferent types which my improved frame is adapted to hold.

As has been stated, my invention relates mainly to a safety razor-frame adapted to hold blades of various makes. To gain-this end I provide a special clamping device and a special form of frameto support and coact with the clamp. The clamping device is provided with a plurality of clamping elements arranged to act in conjunction one with the other to hold certain blades, or to act inde- Specification of Letters Patent.

pendently of each other to hold certain other blades.

The invention may be embodied in different forms, but .I prefer to provide a frame, such as 10, having a depending lip 11 to engage a handle 12, the frame consisting of a top-plate 10 and front plate or guard 13 offset intermediate its upper and lower edges as at '14 to provide a fulcrum surface 15 for a purpose'to be hereinafter described. To gain the best results I prefer to curve the surface 15 as will'be explained.

Forthe passage and action of the clamping elements ofthe clamp, to be described, I provide the guard 13 with communicating openings or slots 16 and 1.7 the slot 17 being extended intothe top-plate 10 as at 17 I The clamping device consists (in this instance) of'a plurality of'yieldable resilient orspring members 18 and 19 curved to form aloop and secured at one end to the top plate 10 as at 20. As can be seen in Fig. 2

the clamp members or arms 18 and 19 are while the function of the arms 19 and 20 is to impart a downward pressure upon the blades approximately in the direction of the arrow 25in Fig. 2. Certain styles of blades will be engaged at the heel portion by the latch 28 and intermediate the heel portion and cutting edge bythe latch 24. In other words, the latch'23 will rest upon the heel 26 of a Star heavy blade and the heel 27 of a Star'wafenblade (see Figs. 7 and 8), while the latch 24: will merelycontact with the blade without exerting any downward pressure,'the said blades being of course engaged by the'stops 28 atthe lower edge of the guard 13." The downward pressure of the clamping arms 18 and 19 will force the blades firmly against the stops 28. As the pressure upon the blade is approximately in the direction of the arrow 25 the tendency will be to force the heel of the blade toward the guard 13. The action will tendto move the cutting edge away from the guard or firmly against'the stops 2-8 owing to the fill crum provided by the curved offset portion of the surface 15 of the guard 13. For the above mentioned style of blades the latch 2% will not be active but will merely rest against the blade.

latch 24 will be inserted into the center opening 29- (Fig. 6) as indicated in Fig. 2, where a Gillette blade is indicated 110 30; In this form of blade the upper latch will be inactive; in fact, it will not touch thecutting edge of the blade adjacent thereto. As will be seen, the latch 24: is inclined or diverges from-the latch 23 and as it is itself yieldable and resilient it is capable of exert-- ing pressure in the direction of the arrow 31, Fig. 2, in addition to the pressure exerted by its supporting elements, i. 6., the arms 18 and 19. The tendency of the pressure of'the arms 18 .and 19, latch 24 and inclination of the said latch will be to force the blade 30, or a Gillette blade, against the fulcrum surface 15as well as against the stops 28, which combination will tend to firmly hold the blade. i l I To retain a blade of the Penn type (indi cated' by 32, Fig. 9) the inclined latch 24 alone will be used. As these blades arequite narrow they will be inserted .in that region of the frame between the latch 24 and stops 28; in other words, these blades will be retained by the latch 24; bearing upon the heel portionSS. As all of these blades are of a standard fixed size it is possible to form a holder that will be suitable for practically all. The formation, of the clamping ele. ments as well as their action obviates the necessity of any supports for the blades, other than the latches 23 and 24:, intermediate the heel and cutting edge of the blades.

To insert an imperforate'blade it is but necessary to force'the latches 23 and 24 upwardly by pressing upon the cross-plate 22 carried by the arms 18 and 19. After. the

I latches have been forced upwardly a blade can be placed in position on the guard-plate and the arms 18 and 19 released so as to cause the latches to engage the blade. To positiona perforated blade, such as the Gillette (Fig; 6) the latch 24 will be caused to engage the center opening 29, while the arms 18 and 19 are in the raised position, after which said arms will be released. 4 What Iclaim as my invention is 1'. A safetyrazor-frame comprising a guard oflset intermediate its upper and lower edges, said offset portion being curved to present a co-nveXed-outer surface, and a plurality of blade engaging latches adapted for holding. a blade independently of each 4 other, together with means common to both of said latches toforce said latches downward and lnward.
